The Clan/Sept History

All Irish surnames have a distinct meaning. The meaning behind the name O Concannon begins when the name originally appeared in Gaelic as O Concheanainn, possibly meaning fair headed hound. The family descends from Cuceannan, who was killed in 991.

The Middle Ages saw a great number of spelling variations for surnames common to the Irish landscape. One reason for these variations is the fact that surnames were not rigidly fixed by this period because the general population was illiterate and could not specify an exact spelling for their names. The following variations for the name O Concannon were encountered in the archives: Concannon, O'Concannon, Cancannon, Concanon, Cancanon, O'Concanon, Connon and many more.First found in Galway, and Roscommon where they held a family seat from ancient times.In the 19th century, thousands of Irish left their English-occupied homeland for North America. Like most new world settlers, the Irish initially settled on the eastern shores of the continent but began to move westward with the promise of owning land. The height of this Irish migration came during the Great Potato Famine of the late 1840s. With apparently nothing to lose, Irish people left on ships bound for North America and Australia. Unfortunately a great many of these passengers lost their lives - the only thing many had left - to disease, starvation, and accidents during the long and dangerous journey. Those who did safely arrive in "the land of opportunities" were often used for the hard labor of building railroads, coal mines, bridges, and canals. The Irish were critical to the quick development of the infrastructure of the United States and Canada. Passenger and immigration lists indicate that members of the O Concannon family came to North America quite early: Patrick Cancannon arrived in New York State in 1811; Michael Concannon who arrived in Philadelphia in 1878; Edward, George, James, Michael, Timothy, arrived in Philadelphia or Boston between 1840 or 1870.
